The photos are small and somewhat out of focus. However, this looks like a type of beetle, possibly a sawtoothed grain beetle, a type of pantry pest.  
Perhaps the beetles were flying around, landed, and got stuck in the fibers of the carpet. 

Management is the same for all types of pantry pests. Potential sources of food for the beetles are numerous. Look for any active infestation most likely in the kitchen or pantry (look in possible spices, bulk grains, dogfood, etc.) and discard. Infested foods should be thrown away and the shelves cleaned thoroughly to eliminate food material and insect eggs or larvae which might be in cracks or corners. Vacuum the shelves and then wash the cupboards with warm soapy water.
Do not spray any food storage areas with insecticides. Clean up any food spills promptly. If you purchase foods in bulk check carefully. Keep food in glass jars, plastic containers, or metal canisters. Do not store products in plastic bags, or cardboard boxes as the insects can chew through.
